The guiding of charged particles through microscopic and, more recently, also macroscopic
capillaries is a remarkable effect discovered in 2002 by Stolterfoht and coworkers. After an …

Studies of charged particle guiding through capillaries in insulating materials, performed
during the last decade, are reviewed in a comprehensive manner. First, the principles of …

Guiding of highly charged ions through tilted capillaries promises to develop into a tool to
efficiently collimate and focus low-energy ion beams to sub-micrometer spot size. One …

When keV energy ions are injected into a tilted insulating capillary, a certain fraction of the
injected ions are transported through the tilt angle of the capillary. This ion guiding …

We have measured the transmission of 230-keV (10-keV/q) Xe 23+ ions through insulating
tapered glass capillaries of microscopic dimensions. The dynamics of charging and …

Production of ion microbeams using tapered glass capillary optics was introduced more than
10 years ago. This technique has drawn attention in terms of both its peculiar transmission …

The transmission of 4.5 keV Ar 7+ ions through a straight cylindrical macrocapillary is
simulated in accordance with the results of a recent experiment. A detailed comparison with …

Transmission experiments of 7–200 keV H 2+ ions through conical multicapillaries with inlet
or outlet diameters of 4/2 μ m and a length of 30 μ m etched in a PC polymer are reported …

The charge relaxation of accumulated charge patches in insulating straight capillaries is
investigated theoretically. The model assumes that charges accumulate only at the inner …

Experimental and theoretical studies are performed to investigate guiding of 4.5-keV Ar 7+
ions through a conical macrocapillary. The tilt angle of the capillary axis relative to the …
